There has been much written about the truthfulness of land-based slots machines. Steve Bourie’s excellent article, “Are Slot Machines Honest?” is an excellent example. This article originally appeared in American Casino Guide 1999. It can be searched online for the title using Google or Yahoo!. The physical, land-based slots machines can offer a variety of “variations”, which are polite and may deceive players. They are all illegal and never happen. However, you should read the entire article.
Online casino slots, on the other hand, use an electronic random number generator (or RNG) that operates inside a large computer program. This program manages the game graphics and player accounts, as well as the statistics for every hand. The instructions for the random number generator are hard-coded and do not change. There is no sense switch (see Bourie article) that can flip the random number generator to make players have worse odds. Concerning control parameters: Each use of the RNG will be identical to the previous use. Although the numbers will be random, the pattern of randomness is constant. This is the real advantage of online software-based casino slots.
Online casino slots have a lower payout percentage than land-based machines, with payout percentages up to 83%. Online gaming has the same winning percentage for each machine as other machines. The payout percentages of many online gaming sites can be viewed. You will notice that they rarely Video slots drop below 95%, which means that the house usually makes a profit of 5%. Most casinos can prove that their payout percentages range from 97% to 98%. It means that you could spend an hour and gamble $100 three times. On average, it will cost $7.50. Players don’t gamble for the average win; the real reward is the high-paying one. The high-paying win is offset by the loss of many players and financing that win.
Are online casino slots really fair? They are. Independent testing laboratories regularly test the software that runs the games (look out for logos at bottom of casino website) and each game can be independently controlled to avoid bias. This is far more than what happens with land-based slots machines, which are appropriately called “one-armed bandsits”.
While players have better odds and are guaranteed to win, no one can guarantee that they will win every game. This is part of the thrill of gambling.
